Specification of Letters Patent.

Patented May 12, 191a.

To all whom it may concern: I I

Be it known that I, CHARLES H. NORTON, acitizen of the United States,residing at \Vorcester, in the county of lVorcester and State ofMassachusetts, have invented a new and useful Open Bearing, of which thefol lowing is a specification.

This invention relates to an open bearing and forms a division ofapplicants prior application Serial No. 633,021, filed June 14,

One object of my invention is to provide an open bearing so constructedthat a. shaft or roll supported upon said bearing may be ground whilethus supported, the parts of the bearing being so arranged that they donot interfere with the grinding operation.

.Another object of my invention is to provide improved devices foradjusting the supporting members of the open bearing.

To the accomplishment of the objects above referred to,.the inventioncomprises the features and combinations of parts hereinafter describedand more particularly pointed out in theappended claims.

A preferred form of my invention is' shown in the drawings in whichFigure 1 1sv an end viewof an open hearing; Fig. 2 is an enlargedse'ctionalview taken along the line 22 of Fig. 1; Figs. 3'.

and 4 are end and side elevations respectively of the setting device];and Fig.5 is an enlarged plan view of the means for clamping the settingdevice in position Fig. 6 is a detail view of the locking bolt forsecuring the headof the setting ,device upon its support: and Fig. 7 isa detail View of the device for clamping the scale rod in position. 1 1

In the embodiment of my invention here in shown, the' bearing comprisesa frame 10 supporting a plurality of radially adjustable bearing members11. The frame 10 may be mounted upon any suitable support 12 and whenfound desirable may be arranged for longitudinal adjustment along' aguide 13,

being held in adjusted position by a bolt 14. The bearing members 11 arearran ed" to be adjusted to a predetermined circum erence and to supportthe rotating roll or shaft R thereon.

As shown in Fig. 1, the bearing members 11 are disposed in two series ofradially arranged slots 14, the uppermost member of the front seriesbeing placed in a plane substantially below. the center of the rotatingshaft so that the grinding wheel WV may contact with the shaft along itshorizontal diameter, The uppermost member of the rear series, however,is arranged in a higher plane than the corresponding member of the frontseries and is adapted to counteract the i I thrust of. the grindingwheel. Each bearing member as shown in Figs. 1 and 2, is pro- ;videdwith an arc-shaped bearing surface upon its upper side and with a pairof oppositely inclined supporting surfaces upon its 4 under side.Arranged within each radial slot .14 s a pan of oppositely. disposedwedge-shaped blocks 15 mounted upon a compound screw 16. The screw 16 ispro-,. vided with a collar 17 fitting a recess 18 in the frame 10, bywhich it is restrained from longitudinal movement. The screw 16 is alsoprovided with an extension 19 adapted to'receive a wrench by which itmaybe adusted.

In order that the bearin surfaces 11 may be accurately set to any esiredcircumference," a setting device is provided comprising a frame 20adapted to be secured to'theguide 13 by-a clamping lever 21. The frameapplication filed September 20 carries a plate 22 upon which isrotatably I mounted a head 23. supporting a horizontal sleeve 24. Thehead 23 is pivoted upon a stud 25 and may be retained in either one oftwo diametrically opposed positions by a spring-pressed locking bolt 26,as shown in Fig. 6. Within the sleeve- 24 is rotatably mounted a stud 27having a head 28 within which is slidably mounted 'a graduated rod 29.The rod 29 may be retained in adjusted position within the head 28 bythe clamping device shown in detail in Fig. 7 and comprisinga threadedsleeve 30 having a threaded stud 31 secured therein, a sleeve 32 looselymounted onsaid stud 31 and a nut 33 threaded on said stud and providedwith a knurled head 34 by which the. same may be turned to clamp the rod29 between the clamping members 30 and 32. One side of the rod 29.

may be slabbed off, as at .35, to receive the graduations, and the head28 may be provided with a block 36 secured by a screw 37, the blockcoacting with the flat side of the rod 29 to prevent the same fromturning as a reference surface by which to read the scale.

Inspection of the drawings will show that:

the axis of the stud 27 is maintained in fixed relation to the guide 13and that consequently, by setting the scale rod 29 to any desired radiusand swinging the same upon the stud 27, the rod may be brought in 0011-.

tact successively with each of the bearing members and that by use ofthe adjusting screw 16 each bearing member may be radially adjusted tothe circumference determined by the rod.

Having thus described my invention, it will be obvious that many changesand modifications therein can be made by one skilled in the art withoutdeparting from thespirit and scope thereof, and I do not wish to belimited to details herein disclosed, but

What I do claim is 1.An open bearing comprising a frame and twovsets ofarc-shaped members carried thereby, the uppermost-support of the frontset being ina plane substantially below that of the uppermost support inthe rear set.

2. An open bearing comprising a frame, a plurality of arc-shaped,supports mounted in radial slots in said frame, wedge-shaped blocksunderlying said supports, andmeans for adjusting said blocks.

3. An open bearing comprising a frame,

and a plurality of arc-shaped supports mounted in radial slots in saidframe, each support having an inclined surface on its frame, the rearside back and an adjusting Wedge engaging the same.

4:. An open bearing comprising a radially slotted frame, a plurality ofarc-shaped supports mounted in the slots in said frame, the

rear side of each support being formed with a pair of inclined surfaces,wedge shaped blocks fitted in oppositely disposed pairs in said slotsunder said supports, and a compound screw threaded into each pair of"blocks for adjusting said support.

5. An open bearing comprising a radially slotted frame, a plurality ofareshaped supports mounted in the slots in said of each support beingformed with a pair of inclined surfaces,

wedge-shaped blocks fitting in oppositely disposed pairs in said slotsunder said supports, and a compound screw having an integral collarreceived in a recess in said frame and having right and left-handscrewthreads engaging threaded openings in a pair of said blocks, saidscrew being also providedwith an extension by which it may be turned tomove said blocks simultaneously and to'thereby adjust one of saidsupports radially. 1 i

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

CHARLES H. NORTON.
